RAG pipeline failures traced to document parsing, not LLM or retrieval

By PulseAugur Editorial · [1 sources] ·

Enterprise Retrieval-Augmented Generation (RAG) systems often fail due to issues in the document ingestion and parsing layer, rather than problems with the LLM or retrieval mechanisms. Standard parsers struggle with complex document structures like multi-page tables, scanned images, and multi-column layouts, silently corrupting data before it reaches downstream components. This article proposes a production-grade ingestion pipeline using Docling and LangChain to address these parsing failures at their source, ensuring better data quality for RAG applications. AI

IMPACT Highlights critical infrastructure challenges in RAG, suggesting improved parsing is key for reliable enterprise AI applications.

RANK_REASON Article discusses a specific technical problem and solution for RAG pipelines, focusing on tooling and implementation.
